Strength in Numbers: A Giant NIR-II AIEgen with One-for-All Phototheranostic Features for Exceptional Orthotopic Bladder Cancer Treatment.	One-for-all phototheranostics that allows the simultaneous implementations of multiple optical imaging and therapeutic modalities by utilizing a single component, is growing into a sparkling frontier in cancer treatment. Of particular interest is phototheranostic agent with emission in the second near-infrared (NIR-II) window. Nevertheless, the practical uses of those conventional NIR-II agents are severely impeded by their unsatisfactory features including insufficient stability, low synthetic yield, to be extended absorption/ emission wavelengths, and inefficient phototheranostic outcomes. Developing exceptional phototheranostic agents is thus highly desirable yet remains formidably challenging. Herein, we synthesized two novel N-heteroacenes-based NIR-II luminogens, namely 2TT-PPT and 4TT-PBPT, by respectively employing pyrene-fused phenaziothiadiazoles and pyrene-fused bisphenaziothiadiazoles as acceptor skeletons. There is strength in numbers by increasing the fusing rings in N-heteroacenes moieties and numbers of appended donors. Compared to less ring-fused 2TT-PPT, the giant molecule 4TT-PBPT shows improved photophysical characteristics, such as enhanced light absorbance, red-shifted wavelengths, higher brightness, favorable reactive oxygen species (ROS) generation, and elevated photothermal conversion efficiency, which render 4TT-PBPT nanoparticles excellent fluorescence-photoacoustic-photothermal trimodal imaging guided photodynamic-photothermal synergistic therapy for orthotopic bladder cancer.	bladder
HLA-G expression associates with immune evasion muscle-invasive urothelial cancer and drives prognostic relevance.	INTRODUCTION: Urothelial bladder cancer is frequent and exhibits diverse prognoses influenced by molecular subtypes, urothelial subtype histology, and immune microenvironments. HLA-G, known for immune regulation, displays significant membranous expression in tumor tissues. METHODS: We studied the protein expression of Human Leucocyte Antigen G (HLA-G) in 241 Muscle-Invasive Bladder Cancer (MIBC) patients, elucidating its potential clinical and biological significance. Protein expression levels were evaluated and correlated with molecular subtypes, histological characteristics, immune microenvironment markers, and survival outcomes. RESULTS: High HLA-G expression associates with poor overall survival (OS) and diseasespecific survival (DSS), independent of clinicopathological parameters. HLA-G expression varies among molecular subtypes and Urothelial Subtype Histology, e.g., elevated expression levels in basal/squamous MIBC and those with sarcomatoid differentiation. Notably, HLA-G is increased in MIBC with an immune evasive microenvironment (high PD-L1 tumor cell expression, NK cell depletion, granzyme B (GZMB)/CD8 ratio reduction, MHC class I (MHCI) expression reduction) that are characterized by immunosuppressive features and poor prognosis. Furthermore, HLA-G correlates with elevated levels of other immune checkpoint proteins (TIGIT, LAG3, CTLA-4), indicating its role in immune evasion. DISCUSSION: Our findings underscore HLA-G's role as a potential prognostic marker and interesting immunotherapeutic target in MIBC. Its impact on immune evasion mechanisms and broad expression, coupled with associations withpoor survival and distinct tumor phenotypes, positions HLA-G as a promising protein for further exploration in developing targeted immunotherapies for MIBC patients.	bladder
Anthocyanins and flavonoids derived from Clitoria ternatea L. flower inhibit bladder cancer growth via suppressing fatty acid synthesis mediated by SREBP1 pathway.	Clitoria ternatea L. flowers are used as traditional herbal medicines and are known for their advanced pharmacological activities. Flavonoids and anthocyanins reportedly contribute to the therapeutic properties of C. ternatea flowers; however, their potential anti-bladder cancer effects and molecular mechanisms remain unknown. In this study, flavonoid- and anthocyanin-rich samples from C. ternatea flowers (DDH) are prepared via macroporous resin-based extraction coupled with an efficient and reliable two-dimensional UPLC-DAD-MS/MS method. In vitro and in vivo studies reveal that DDH can inhibit bladder cancer cell growth and enhance the anti-bladder cancer activity of cisplatin. RNA-seq combined with KEGG analysis reveals that fatty acid synthesis is closely related to the anti-bladder cancer effect of DDH. Furthermore, DDH dose-dependently reduces cellular fatty acid levels in bladder cancer cells, and the addition of fatty acids significantly mitigates DDH-induced cell growth inhibition. Subsequent findings reveal that DDH downregulates sterol regulatory element-binding protein 1 (SREBP1), a key transcriptional regulator of de novo fatty acid synthesis in cancer cells, and its downstream targets (FASN, SCD1, and ACC). Additionally, this study demonstrates that gallic acid not only enhances the stability of DDH but also synergistically potentiates its anti-bladder cancer activity. Our study suggests that targeting the SREBP1 pathway is an effective strategy in bladder cancer therapy, and the ability of DDH to induce cell death by inhibiting the SREBP1 pathway and its good tolerance in mice make it a promising strategy for preventing and treating bladder cancer.	bladder
Efficacy and safety of pembrolizumab in patients with advanced urothelial carcinoma deemed potentially ineligible for platinum-containing chemotherapy: Post hoc analysis of KEYNOTE-052 and LEAP-011.	BACKGROUND: First-line pembrolizumab monotherapy is a standard of care for platinum-ineligible patients with advanced urothelial carcinoma (UC). No global standardized definition of platinum ineligibility exists. This study aimed to evaluate the efficacy and safety of pembrolizumab monotherapy in patients with UC who met various criteria for platinum ineligibility. METHODS: Patients from KEYNOTE-052 and LEAP-011 deemed potentially platinum ineligible were pooled for this post hoc exploratory analysis as follows: group 1: Eastern Cooperative Oncology Group performance status (ECOG PS) 2; group 2: ECOG PS 2 and age ≥80 years, renal dysfunction, or visceral disease; and group 3: any two other factors regardless of ECOG PS. Patients received pembrolizumab 200 mg intravenously every 3 weeks. End points included objective response rate (ORR), progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors, version 1.1, by blinded independent central review, overall survival (OS), and safety. RESULTS: A total of 612 patients treated with pembrolizumab from KEYNOTE-052 (n = 370) and LEAP-011 (n = 242) were included; the median (range) follow-up was 56.3 months (51.2-65.3 months) and 12.8 months (0.2-25.1 months), respectively. For group 1, ORR was 26.2%, median PFS was 2.7 months, and median OS was 10.1 months. For group 2, ORR ranged from 23.5% to 33.3%, median PFS ranged from 2.1 to 4.4 months, and median OS ranged from 9.1 to 10.1 months. For group 3, ORR ranged from 25.7% to 27.9%, median PFS ranged from 2.1 to 2.8 months, and median OS ranged from 9.0 to 10.6 months. Treatment-related adverse event rates were consistent across groups. CONCLUSIONS: Frontline pembrolizumab has consistent antitumor activity and safety in patients with advanced UC categorized as potentially ineligible for platinum-based chemotherapy, regardless of the variable definitions of platinum ineligibility used.	bladder
Immune Checkpoint Blockade Therapies Efficacy and Toxicity in Patients With Impaired Renal Function in Metastatic Bladder Cancer.	BACKGROUND: In this study, we reported the real-life results of data from impaired renal patients with urothelial carcinoma who were treated with ICTs. METHODS: The patients were categorized into 3 different groups GFR ≥60mL/min (normal), 60mL/min-30mL/min (low), and less than 30 mL/min (very low) based on GFR. The primary endpoints were the overall response rate (ORR), overall survival (OS), duration of response with ICT, and safety. Median follow-up and OS were estimated by using the Kaplan-Meier method. RESULTS: One hundred-five (60.3%) of patients were GFR normal, 26.4% were GFR low with 30mL/min-60mL/min, and 13.2% were very low group. ORR for GFR normal, low and very low groups were 36% (n = 38), 26% (n = 12) and %31 (7); P = .2, respectively. The median duration of response for GFR normal, low and very low groups were 47.2 months (95% CI, 24.5-51.4), 33.1 months (95% CI, 26.9-47), and 23.5 months (95% CI, 12.2-43.7); P = .01, respectively. The Median OS rate for GFR normal, low and very low groups were 11.9 (7.2-16.5) months, 4.7 (1.8-7.7) and 6.8 (1.1-13.6) months, P = .015, respectively. In addition, GFR <60 ml/min HR = 1.6; 95% CI 1.12-1.80; P = .02, maintained a significant association with OS in multivariate analysis. CONCLUSIONS: Long-term follow-up of real-world data confirms that the overall survival rate and durable response rate with ICT were higher in patients with GFR >60mL/min. On the other hand, we demonstrated that ICT was effective and a durable response seen in a group of patients with renal inpairement who did not have an effective systemic treatment option.	bladder
Increased Tobacco Taxation Associated With Decreased Consumption and Bladder Cancer Incidence.	INTRODUCTION: The temporal relationship between smoking exposure and bladder cancer (BC) diagnosis remains ill defined. This study aims to cross-correlate and temporally associate changes in US tobacco tax and consumption with BC incidence. METHODS: US tobacco consumption, tobacco tax data, and BC incidence rates from 1975 to 2019 were retrieved. A cross-correlation lag time for tobacco tax and consumption on BC incidence was calculated while controlling for national health expenditure. Proxied lag weighted semi-log linear models were used to determine the rate of change in BC incidence rates associated with a 1% change in tobacco tax percentages on a national and state level. RESULTS: A 1% increase in tobacco tax was associated with a 1.77% decrease in BC incidence over a 6-year period (R(2) = 0.9687, P = .00044). Twenty-two states had a statistically significant decline in BC incidences correlated with increasing tobacco taxation. Reduction in BC incidence > 0.5% was observed in states along the western and eastern US borders. Montana, Utah, Nebraska, Arkansas, and Tennessee did not have decreasing BC incidences from tobacco tax increases. California had the most drastic decline in BC incidence (1.98%). Nationally, tobacco consumption decrease in 1 pack per capita was associated with a 0.47% decrease in BC incidence over a 28-year period (R(2) = 0.984, P = .00011). CONCLUSIONS: Declining US tobacco consumption may indicate significant reduction in BC incidence through 2047. Primary prevention through adaptation of state-legislated tax changes may contribute to a reduction in BC incidence in states lying within the Central United States. A national tobacco tax initiative can be considered given the improvement in population health.	bladder
Prognostic value of isolated tumor cells and micrometastasis of lymph nodes in invasive urinary bladder cancer.	INTRODUCTION: The prognostic significance of nodal micrometastasis and isolated tumor cells (ITC) in urinary bladder cancer (UBC) is unknown. We aimed to evaluate the prevalence, clinical impact, and clinicopathological characteristics of nodal micrometastasis and ITC in UBC. MATERIALS AND METHODS: A total of 124 patients with UBC undergoing surgery were investigated. Detection of micrometastasis and ITC was performed using pancytokeratin immunohistochemistry (IHC). Histopathologic and clinical findings were correlated with patients' outcome. RESULT: IHC detected nodal micrometastasis and ITC (pNmi group) in 12.9% (13/101) of originally node-negative patients and in 26.1% (6/23) of originally node-positive patients (pN+ group). The remaining 88 were truly node-negative patients (pN0 group). After IHC, all 13 patients in the pNmi group were upstaged from pN0 to pN1-2 and one patient in the pN+ group was changed from pN1 to pN2. Nodal micrometastasis and ITC were significantly associated with mixed urothelial carcinoma (UC) (p = 0.002), UC with discohesive pattern (p = 0.006), glandular differentiation (p = 0.043), lymphovascular invasion (p = 0.009), and budding-like tumor cell clusters (p = 0.002). The pNmi group had significantly worse cancer-specific survival than the pN0 group in univariate (p = 0.004) and multivariate (p = 0.040) analysis. CONCLUSION: IHC frequently identified nodal micrometastasis and ITC in originally node-negative UBC patients on routine pathological examination. Nodal micrometastasis and ITC were independently associated with cancer-related mortality in UBC. IHC might be selectively used to detect micrometastasis and ITC in UBC having specific pathological features.	bladder
Integrating single cell and bulk RNA sequencing data identifies RBM17 as a novel response biomarker for immunotherapy in bladder cancer.	Checkpoint inhibitors (CPIs) have been widely applied in the treatment of patients with bladder cancer (BLCA). However, there is still unmet need to dissect response predict biomarkers. To uncover CPI response-related marker genes in cancer cells, we utilized SCISSOR, integrating single-cell RNA and bulk RNA sequencing data. Transcriptomic and clinical data from IMvigor210, UNC-108, and BCAN/HCRN datasets were collected to evaluate and validate the identified biomarkers and signatures. Additionally, we analyzed TCGA-BLCA and local-BLCA RNA-seq data to investigate alternative splicing events (ASEs). Cell viability was assessed in T24 and UMUC3 cells with RBM17 upregulation or downregulation. Through SCISSOR analysis, we discovered that the expression levels of RBM17, TAP1, and PSMB8 were significantly associated with CPI response. Since PSMB8 displayed a highly positive correlation with TAP1, we developed a CPI response score (CRS) signature based on the expression profiles of RBM17 and TAP1. The CRS demonstrated robust predictive capacity in IMvigor210, UNC-108, and BCAN/HCRN datasets and was associated with higher tumor mutational burden (TMB), PD-L1 expression, and unique genomic features. Notably, RBM17 was not linked to the clinical outcomes of BLCA patients but positively correlated with BLCA cell proliferation in vitro. In the meantime, RBM17 was correlated with higher activity in core biological pathways, including antigen processing machinery, CD8 + T effector cells, cell cycle, DNA damage repair, epithelial-mesenchymal transition, histone regulation, and immune checkpoints. Moreover, the high-RBM17 group showed enrichment of LumU/Ba/sq subtypes but fewer FGFR3 alterations. Lastly, RBM17 significantly upregulated ASEs in BLCA samples, leading to higher neoantigen levels, a more inflamed tumor microenvironment, and improved CPI response. RBM17 is associated with higher ASEs and neoantigen levels, thereby potentiating the efficacy of CPI in BLCA. The established predictive signature, utilizing only two genes, has the potential to streamline clinical applications, providing a cost-effective alternative to expensive genomic, transcriptomic, and biological feature tests.	bladder
Precise grading of non-muscle invasive bladder cancer with multi-scale pyramidal CNN.	The grading of non-muscle invasive bladder cancer (NMIBC) continues to face challenges due to subjective interpretations, which affect the assessment of its severity. To address this challenge, we are developing an innovative artificial intelligence (AI) system aimed at objectively grading NMIBC. This system uses a novel convolutional neural network (CNN) architecture called the multi-scale pyramidal pretrained CNN to analyze both local and global pathology markers extracted from digital pathology images. The proposed CNN structure takes as input three levels of patches, ranging from small patches (e.g., 128 × 128 ) to the largest size patches ( 512 × 512 ). These levels are then fused by random forest (RF) to estimate the severity grade of NMIBC. The optimal patch sizes and other model hyperparameters are determined using a grid search algorithm. For each patch size, the proposed system has been trained on 32K patches (comprising 16K low-grade and 16K high-grade samples) and subsequently tested on 8K patches (consisting of 4K low-grade and 4K high-grade samples), all annotated by two pathologists. Incorporating light and efficient processing, defining new benchmarks in the application of AI to histopathology, the ShuffleNet-based AI system achieved notable metrics on the testing data, including 94.25% ± 0.70% accuracy, 94.47% ± 0.93% sensitivity, 94.03% ± 0.95% specificity, and a 94.29% ± 0.70% F1-score. These results highlight its superior performance over traditional models like ResNet-18. The proposed system's robustness in accurately grading pathology demonstrates its potential as an advanced AI tool for diagnosing human diseases in the domain of digital pathology.	bladder
Primary Chemoablation of Recurrent Low-Grade Intermediate-Risk Nonmuscle-Invasive Bladder Cancer With UGN-102: A Single-Arm, Open-Label, Phase 3 Trial (ENVISION).	PURPOSE: We evaluate the efficacy and safety of UGN-102 chemoablation for the primary treatment of patients with recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer. MATERIALS AND METHODS: ENVISION is an ongoing, multinational, single-arm, phase 3 study in patients with a biopsy-proven recurrence of untreated low-grade intermediate-risk nonmuscle-invasive bladder cancer. Patients received 6 weekly intravesical instillations of UGN-102 (mitomycin; outpatient setting) and were evaluated at 3 months. Patients achieving complete response (CR; negative cystoscopic examination, cytology, and for-cause biopsy) were surveilled regularly until recurrence, progression, or death. Patients who remain disease-free will be followed up to 5 years, and further results will be reported in the future. RESULTS: Of 240 patients enrolled, 228 (95%) received all 6 planned doses; 191 (80%; 95% CI, 73.9-84.5) achieved CR at 3 months, with an 82% (95% CI, 75.9-87.1) probability of response 12 months later. Median duration of response was not estimable over a median 13.9-month follow-up period. The most common adverse events (≥5.0% of patients) were dysuria, hematuria, UTI, pollakiuria, fatigue, and urinary retention; generally mild/moderate and resolved/resolving. Serious adverse events were observed in 29/240 (12.1%); 2 were treatment related (urinary retention/urethral stenosis), and both resolved. CONCLUSIONS: Primary chemoablation with UGN-102 in patients with recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer resulted in an 80% CR rate. Patients achieving a CR had an 82% likelihood of remaining disease-free 1 year later. The benefit-risk profile was favorable, supporting UGN-102 as a nonsurgical alternative for transurethral resection of bladder tumors in this patient population. Limitations of this study included lack of tumor sizing after the diagnostic biopsy. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05243550.	bladder
Microbiome and bladder cancer: the role of probiotics in treatment.	Bladder cancer (BCa) remains a significant global health challenge, with increasing interest in the role of the bladder microbiome in its pathogenesis, progression and treatment outcomes. The complex relationship between bladder cancer and the microbiome, as well as the potential impact of probiotics on treatment effectiveness, is currently under investigation. Research suggests that the microbiota may influence BCa recurrence prevention and enhance the efficacy of the Bacillus Calmette-Guérin (BCG) vaccine. Recent studies reveal differences in the bladder microbiome between individuals without bladder cancer and those with the disease. In the healthy bladder, Streptococcus and Lactobacillus are consistently identified as the most prevalent genera. However, in men, the predominant bacterial genera are Staphylococcus, Corynebacterium and Streptococcus, while in women with bladder cancer, Gardnerella and Lactobacillus are dominant. Probiotics, particularly Lactobacillus spp., can exhibit anti-tumor properties by competing with pathogenic strains involved in carcinogenesis or by producing regulatory substances. They regulate cancer signaling, induce apoptosis, inhibit mutagenic activity, downregulate oncogene expression, induce autophagy, inhibit kinases, reactivate tumor suppressors and prevent metastasis. These mechanisms have shown promising results in both preclinical and some clinical studies.	bladder
Trends in the use of immediate postoperative intravesical chemotherapy following transurethral resection of bladder tumors.	PURPOSE: The use of immediate postoperative intravesical chemotherapy (IVC) following transurethral resection of bladder tumor (TURBT) has been shown to reduce the rate of recurrence of nonmuscle invasive bladder cancer. Historically, utilization of IVC following TURBT has been low. We sought to determine the rate of immediate postoperative IVC following TURBT, as well as assess factors that may influence its use. METHODS: We utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to assess the rates of IVC between the years 2016 to 2021. All patients who underwent TURBT based on appropriate procedure codes were initially included. Patients with an additional procedure code for the administration of IVC were identified. RESULTS: From 2016 to 2021, 50,295 patients underwent TURBT for bladder cancer. There were 21,544 (43%) small, 18,135 (36%) medium, and 10,616 (21%) large tumors treated. In total, 2,833 (5.6%) patients received IVC. Use of IVC was associated with surgery performed in an elective setting, those who did not receive preoperative blood transfusion, and shorter operative time. Receipt of chemotherapy was more common in the later years examined. CONCLUSIONS: The rate of use of IVC remains very low. Ongoing study and improvement initiatives are in place, though these predominantly are assessing academic centers. Further study and quality improvement should be performed and include community practice settings.	bladder
Exploring the molecular pathways of the activation process in PPARγ recurrent bladder cancer mutants.	The intricate involvement of Peroxisome Proliferator-Activated Receptor Gamma (PPARγ) in glucose homeostasis and adipogenesis is well-established. However, its role in cancer, particularly luminal bladder cancer, remains debated. The overexpression and activation of PPARγ are implicated in tumorigenesis. Specific gain-of-function mutations (M280I, I290M, and T475M) within the ligand-binding domain of PPARγ are associated with bladder cancer and receptor activation. The underlying molecular pathways prompted by these mutations remain unclear. We employed a dual-basin structure-based model (db-SBM) to explore the conformational dynamics between the inactive and active states of PPARγ and examined the effects of the M280I, I290M, and T475M mutations. Our findings, consistent with the existing literature, reveal heightened ligand-independent transcriptional activity in the I290M and T475M mutants. Both mutants showed enhanced stabilization of the active state compared to the wild-type receptor, with the I290M mutation promoting a specific transition route, making it a prime candidate for further study. Electrostatic analysis identified residues K303 and E488 as pivotal in the I290M activation cascade. Biophysical assays confirmed that disrupting the K303-E488 interaction reduced the thermal stabilization characteristic of the I290M mutation. Our study demonstrates the predictive capabilities of combining simulation and cheminformatics methods, validated by biochemical experiments, to gain insights into molecular activation mechanisms and identify target residues for protein modulation.	bladder
